Fox News set the bar for RTCA after-parties with its disco extravaganza in 2004, and this year, MSNBC will try to top it with Rachel Maddow, who will be mixing cocktails behind the bar. If that’s not enough, there will also be a chocolate fountain.

More than 400 guests are expected to cross the street from the Convention Center when the dinner ends to an MSNBC logo-swathed Washington Historical Society, at 801 K Street.

Maddow won’t be at the dinner; she’ll head to the party after doing her show; her “special cocktail” is being kept a tightly guarded secret. But an insider reveals the rest of the menu will include mini-milkshakes, ice cream bar, the chocolate fountain and breakfast, for those who stay to the bitter end. And a Starbucks Coffee Bar, in honor of the new “Morning Joe” sponsor. There won’t be a band, just a DJ.

MSNBC muscled in on the party after Fox News backed out. MSNBC was initially told Fox had locked up the Historical Society, the only party venue around in that part of town, and “It was this space or nothing,” said an insider. No official word on why Fox may have changed its mind but someone in the know said it was due to the ever-changing dinner date, from April 2 to June 4 to June 19, a Friday-and Father’s Day weekend, no less. (Many on-air talent types at all the networks are begging off this year because of the timing.)

Tim Daly (“Private Practice”), Justin Long (“He’s Just Not That Into You”) and Richard Belzer (“Law & Order”) will be lighting up USA Today’s tables at the WHCD, along with Deputy White House Chief of Staff Mona Sutphen, Dept. of Transportation Secretary Ray LaHood and Michelle Obama staffer Jocelyn Frye, according to FishbowlDC.
